In December 2018, Wellesley was designated a "SolSmart Silver" community for making it faster, easier and more affordable for homes and businesses to go solar.

Currently, the Town has:

98 Residential solar installations generating 656 MWHs/year

11 Commercial solar installations generating 166 MWHs/year

3 WMLP installations generating 97 MWHs/year

Together these solar systems generate 919 MWHs/year of clean renewable energy in the Town of Wellesley.

WMLP has also entered into a Letter of Intent to lease the roof of a private development at 900 Worcester Street in order to install approximately 1 MW of rooftop solar on the building. Beginning in the Spring of 2019, this arrangement is expected to double the amount of solar power in town.

In 2014, the Town of Wellesley launched the highly successful More Power to Choose program. This solar campaign resulted in rooftop solar on over 75 residences and on three Houses of Faith – Temple Beth Elohim, Village Church and Friends Meeting House. During the More Power to Choose campaign, the Wellesley Municipal Light Plant (WMLP) provided $115,000 in rebates. While More Power to Choose has ended, Wellesley and the WMLP plan to pursue another campaign in 2019 following implementation of a Solar Massachusetts Renewable Target (SMART) Program for municipal light plant towns. In the meantime, you still can get solar for your home.
